The discovery of two remarkably well preserved, two-million-year-old fossils of an adult female and young male, known as Australopiitecus sediba, has been hailed as one of the most important archaeological discoveries in history. The fossils reveal what may be one of humankind's oldest ancestors.Berger believes the skeletons they found on the Malapa site in South Africa could be the "Rosetta stone that unlocks our understanding of the genus Homo" and may just redesign the human family tree.Berger, an Eagle Scout and National Geographic Grantee, is the Reader in Human Evolution and the Public Understanding of Science in the Institute for Human Evolution at the University of Witwatersrand, Johannesburg, South Africa.The focus of the book will be on the way in which we can apply new thinking to familiar material and come up with a breakthrough. Marc Aronson is particularly interested in framing these issues for young people and has had enormous success with this approach in his previous books: Ain't Nothing But a Man and If Stones Could Speak.Berger's discovery in one of the most excavated and studied areas on Earth revealed a treasure trove of human fossils--and an entirely new human species--where people thought no more field work might ever be necessary. Technology and revelation combined, plus a good does of luck, to broaden by ten times the number of early human fossils known, rejuvenating this field of study and posing countless more questions to be answered in years and decades to come.

    The New York Times bestselling and National Book Award winning In the Heart of the Sea, soon to be a major motion picture directed by Ron Howard, adapted by the author for young readers. On November 20, 1820, the whaleship Essex was rammed and sunk by an angry whale.  Within minutes, the twenty-one-man crew, including the fourteen-year-old cabin boy Thomas Nickerson, found themselves stranded in three leaky boats in the middle of the Pacific Ocean with barely any supplies and little hope.  Three months later, two of the boats were rescued 4,500 miles away, off the coast of South America.  Of the twenty-one castaways, only eight survived, including young Thomas.  Based on his New York Times best-seller In the Heart of the Sea, Nathaniel Philbrick recreates the amazing events of the ill-fated Essex through the sailors own first-hand accounts, photos, maps, and artwork, and tells the tale of one of the great true-life adventure stories."Horrifyingly engrossing." —Kirkus Reviews"A compelling saga of desperation and survival." —School Library Journal

    They are also one of the most endangered species in the world. For many years, mountain gorillas have faced the threat of t death at the hands of poachers. Funds raised by “gorilla tourism”––bringing people into the forest to see these majestic animals––have helped protect gorillas. This tourism is vital, but close contact between gorillas and people has brought a new threat to the mountain gorillas: human disease.The Mountain Gorilla Veterinary Project is a group of courageous and talented scientists working to save the mountain gorilla population in Rwanda and Uganda. The "Gorilla Doctors" study the effects of human exposure, document the daily lives of the gorillas, provide emergency care to injured animals, and even act as foster parents to an orphaned gorilla baby named Fearless. Through engaging text and stunning photographs, Pamela Turner takes readers on an exploration like no other in this gripping tale of science, nature, and conservation.

As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's discovery gave scientists insight into the delicate balance of ecosystems. Follow science in action as Brent conducts the research that led to this major discovery.

    Montgomery sees a rattlesnake flattened on the side of the road, her first instinct is to pick it up and dissect it--she's always wanted to see how a snake's fangs retract when they close their mouths, and it's not exactly safe to poke around in a live reptile's mouth. A wildlife researcher with a special penchant for the animals that litter the roadways, Heather isn't satisfied with dissecting just one snake. Her fascination with roadkill sets her off on a journey from her own backyard and the roadways of the American South to scientists and kids in labs and homes across the globe. From biologists who use the corpses of Tasmanian devils to investigate cures for a contagious cancer, to a scientist who discovered a whole new species of bird from a single wing left behind, to a boy rebuilding animal bodies from the bones up, to a restaurant that serves up animal remnants, Heather discovers that death is just the beginning for these creatures. This engaging narrative nonfiction is an eye-opening and irreverent look at the dead and dying animals that we pass by without a second thought--as well as a fascinating insight to the scientific research process.
